Flexible hybrid separation system for hydrogen recovery from natural gas grids

Tuberías de hidrógeno

Design, scaling and demonstration of a new flexible hybrid separation system for the recovery of hydrogen transported in natural gas grids in relevant industrial conditions. The separation system combines three technologies: membranes, electrochemical separation and TSA (Temperature Swing Adsorption), reducing the cost of hydrogen recovery.

System designed to separate H2 present in the natural gas grid in low concentrations (≤10 %). Membrane technology enables H2 to be recovered in low content mixtures (2-10%). Electrochemical separation of hydrogen (EHP) is optimum for “very low H2 contents” (<2 %). The TSA (Temperature Swing Adsorption) purifies the H2 based on the humidity produced upstream in both systems.

The construction, operation and validation of a prototype in relevant industrial conditions for continuous and transitory loads is contemplated.

We are participating in the development of two types of membranes for the recovery of hydrogen from low concentration streams (2-10%): Pd based membranes for medium and very low pressures, and Carbon Molecular Sieve (CMS) membranes for higher pressures.
